Introduction The volar locking plate has been widely used for unstable distal radius fractures to provide early recovery of wrist function. Volar plate prominence to the watershed line has been reported to be related to flexor tendon irritation, and avoid implant prominence in this area was suggested. On the other hand, marginal distal radius fracture patterns required the plate to cross the watershed line, making conflict over plate positioning on marginal distal radius fractures. This study compared functional outcomes in patients with marginal distal radius fractures treated with two different implants. Materials and methods A retrospective study was conducted, all patients who received a Synthes 2.4 mm LCP or an Acumed Acu-Loc VLP between January 2015 and December 2018 were reviewed. The marginal distal radius fracture pattern was the most distal horizontal fracture line within 10 mm of the lunate fossa’s joint line. The primary outcomes including patient-reported pain scores, range of motion, and grip strength were assessed. Secondary outcomes included patient-based subjective satisfaction scores of the injured wrist and hand function. The Mayo Wrist Score and the requirement for a secondary procedure related to hardware complications were also recorded. Results Forty-two patients met our inclusion criteria. Twenty-one patients were treated with the Synthes 2.4 mm LCP, and 21 patients with the Acumed Acu-Loc VLP. The primary outcome revealed that post-operative range of motion (P = 0.016) and grip strengths (P = 0.014) were significantly improved in the Acu-Loc VLP group. The MAYO wrist score in the Acu-Loc VLP group was also significantly better (P = 0.006). Conclusions Despite advances in implant designs, flexor tendon irritation or rupture is still a complication following distal radius’s volar plating. We believe the Acumed Acu-Loc VLP design provided better functional outcomes than the Synthes 2.4 mm LCP if appropriately and carefully placed into its designed-for position. This positioning results in promising patient satisfaction when treating marginal distal radius fractures.

Background: The volar locking plates have been widely used in a variety of distal radius fractures, but they still have several limitations when dealing with small fragments located around the watershed line with widely reported complications. The volar rim fragments play a critical role in radiocarpal joint stability and failing to secure the volar rim fragment usually results in carpal instability, subluxation, or even dislocation. This study investigates clinical outcomes in the use of a novel implant, the Trident distal radial (TDR) locking plate to treat distal radius fracture with the intermedium column edge (lunate fossa volar rim) fragment involvement. Methods: A retrospective study of 25 patients was conducted, all patients had intermedium column fractures with lunate fossa volar rim involvement and treat with the TDR between January 2016 and December 2019. The clinical assessment outcomes included VAS Pain, PRWE, and DASH scores. Objective measurements included ROM of the injured wrist and grip strength. Final radiographs were used to evaluate radial inclination, volar tilt, ulnar variance, and distal radioulnar joint instability. Secondary operations related to hardware complications were also recorded. Results: The outcome revealed that the mean VAS Pain Score was 1.3, mean DASH score was 10.5, and mean PRWE score was 9.3. Objective measurements revealed good ROM recovery and an 89% gripping strength recovery compared with contralateral hand. Radiographic measurements revealed good maintenance of volar tilt, radial inclination, and mean ulnar variance. There were no complications related to the implant and all fracture sites were union. Conclusion:We believe that the TDR provided more stable fixation among distal radial fractures that predominantly involved the intermedial column and volar rim fragment, and allowing early rehabilitation. We could obtain excellent results in the wrist ROM, gripping power, and Pain Score (VAS).

Osteomyelitis from a retained foreign body should be included in the differential diagnosis of any osteolytic lesion of the foot. We report here a case of a 59-year-old man who presented with swelling over the dorsolateral aspect of the right foot. Plain x-ray showed an osteolytic lesion that mimicked a pseudotumor. Magnetic resonance imaging (MRI) showed multilocular fluid collection over the right cuboid with a hypointense lesion over the plantar fascia. The patient underwent surgery and a rubber fragment (1 cm × 0.8 cm) was removed from his foot that had been present for two years following a stabbing injury. The patient fully recovered without complication or disability.

Introduction: The volar locking plate has been widely used for unstable distal radius fractures to provide early recovery of wrist function. Volar plate prominence to the watershed line has been reported to be related to flexor tendon irritation, and avoid implant prominence in this area was suggested. On the other hand, ultra-distal radius fracture patterns required the plate to cross the watershed line, making conflict over plate positioning on ultra-distal radius fractures. This study compared functional outcomes in patients with ultra-distal radius fractures treated with two different implants.Materials and Methods: A retrospective study was conducted, all patients who received a Synthes 2.4mm LCP or an Acumed Acu-Loc VLP between January 2015 and December 2018 were reviewed. The ultra-distal fracture pattern was the most distal horizontal fracture line within 10 mm of the lunate fossa's joint line. The primary outcomes including patient-reported pain scores, range of motion, and grip strength were assessed. Secondary outcomes included patient-based subjective satisfaction scores of the injured wrist and hand function. The Mayo Wrist Score and the requirement for a secondary procedure related to hardware complications were also recorded. Results: Forty-two patients met our inclusion criteria. Twenty-one patients were treated with the Synthes 2.4 mm LCP, and 21 patients with the Acumed Acu-Loc VLP. The primary outcome revealed that post-operative range of motion (P = 0.016) and gripping strengths (P = 0.014) were significantly improved in the Acu-Loc VLP group. The MAYO wrist score in the Acu-Loc VLP group was also significantly better (P = 0.006). Conclusions: Despite advances in implant designs, flexor tendon irritation or rupture is still a complication following distal radius's volar plating. We believe the Acumed Acu-Loc VLP design provided better functional outcomes than the Synthes 2.4 mm LCP if appropriately and carefully placed into its designed-for position.
